How to Value Excess Stock Before You Sell It

Throw out the two numbers you already have

Cost price is sunk. It tells you what a past decision cost, not what a future buyer will pay, and clinging to it is the single biggest reason stock sits unsold for years.

Retail price is aspirational. It is the price at which the item did not sell, which is precisely why it is still in your warehouse.

The number that matters

What comparable items are currently selling for, second hand or clearance, to real buyers, this month. Not asking prices. Sold prices.

You can check this yourself in about twenty minutes. Search a representative sample of your items on the marketplaces, filter to completed or sold listings, and write down what they actually went for. Do ten items across your range and you will have a far better picture than any spreadsheet valuation.

Then apply the three discounts

1. 1Condition. Sealed and current sits at the top. Opened or returned sits well below it. Damaged sits below that again.
2. 2Depth. One unit of forty different products is worth less per unit than forty of one, because every distinct product carries its own handling cost.
3. 3Effort. Whatever it costs somebody to photograph, list, pack and ship each item comes out of the number, whether that somebody is you or an agent.

That third discount is the one businesses forget, and it is usually the largest on low value goods. An item worth six pounds and an item worth six hundred cost roughly the same to handle.

Sanity check against the published ranges

Published liquidation research puts recovery at roughly five to thirty percent of original retail depending on condition and channel. If your own valuation is landing far above that band, check your assumptions. If it is landing below it, you may be about to accept a poor offer.

Two figures, not one

Produce a bulk figure and an individual figure, because they answer different questions. The bulk figure is what somebody would pay to take the whole thing away today. The individual figure is what the contents would make if they were sold one at a time to the people who want them.

The gap between those two numbers is the value of doing the work. Whoever does the work captures it. If you sell in bulk, the buyer captures it. If you consign, you keep the larger share of it and somebody else does the work.

Or get it valued properly for nothing

Valuing your own stock is useful but it is guesswork against limited data. Somebody selling this category every day already knows what these items make, because they watched a hundred of them sell last month.

There is no reason for that to cost you anything. Send photographs or a rough list and get a real number back, then check it against your own workings.
